Imprecise and low quality drawing about reframework-d2d

[cursey]

The precision of positioning when using d2d.* is lower than when using draw.*. On videos below the health bar is drawn using draw.world_to_screen(monster.position). Using those coordinates in d2d.fill_rect gives pretty shaky results while draw.filled_rect is drawn smoothly.

This is entirely because d2d updates at a lower rate than the draw API (currently hardcoded to update at 30hz). The rationale for this is simple. Many overlays do quite a bit of work in their draw functions and can cause a non-negligible performance impact for users if ran every single frame.

I plan on making the rate at which d2d updates user configurable, I just didn't get to it in time for first release.

The quality of text is also seems lower.

You're using a different font so I can't tell what you mean. Can you show a clear example of how the quality is lower?

If you want to do a direct comparison, install Roboto Medium on your computer and use that for REFramework-D2D to really compare the results.

Fixed in 2da8447. Make sure to copy the new /scripts/autorun/reframework-d2d.lua over so you can configure the max update rate yourself. The default has been increased to 60hz though (instead of 30hz).

(Also maybe rename fill_rect to filled_rect to match one from imgui?)

Fixed in 9a55217

I've also improved error handling and fixed the freezing issue in abfdda2.

Let me know if this addresses all the reported issues for you.

I think I've probably fixed this in 0edfaf9.

I see. As always thank you for your hard work. I automatically assumed it is at least 60Hz so didn't think of from that perspective. Allowing user to configure it is a good choice.
Improvement suggestion: maybe add auto refresh rate option: when enabled refresh rate matches the refresh rate of the screen (or the game)?

Font quality (on the old version):
roboto_font = d2d.create_font("Roboto", 13, true):
(should i be passing "Roboto Medium" or "Roboto-Medium" or "RobotoMedium"?)

roboto_font = d2d.create_font("Roboto", 13, false):

Idk something feels off. For example the top of t is slightly blurred on d2d bold font.

Performance note: Drawing 50-100 small monster UIs caused me 1 fps drop (from 96 to 95) on old version (30Hz) on gtx1070.

I think its user preference at that point. I personally prefer the plugins output in your example (both bold and regular). I'm a big fan of DirectWrite output though so I may be biased.

[GreenComfyTea]

I am fan of DirectWrite too. But doesn't imgui uses DirectWrite too? I would have expected same results.

You are right about this thou xD

imgui uses stb_truetype which is a very simple (compared to DirectWrite) font rasterizer.

[GreenComfyTea]

Fair enough. I have no more complaints xD

This can be accomplished by just setting the max update rate to 300 (or any rate higher than their normal framerate). Assuming people don't hit 300 FPS, it will just run as fast as their FPS.
